Key to American species of Premnophilus (females only)

1 Posterolateral margin of declivity not raised, declivital face flattened or sulcate, marginal denticles absent ( Figs. 7 E , 9 E , 10 E , 12 E )............................................................................................... 2

- Posterolateral margin of declivity raised, rounded, declivital face concave, marginal denticles present ( Figs. 6 E , 8 E )...... 5

2 Declivital face flattened, all denticles confused, uniform in size ( Figs. 11 E ) wilsoni Atkinson & Flechtmann

- Declivital face weakly sulcate at base, denticles on interstria 1 generally larger than others, uniseriate ( Fig. 7 E , 9 E , 10 E ).. 3

3 Vestiture on elytral disc mostly absent, granules on interstria 1 of declivity not noticeably larger than others ( Fig. 8 )................................................................................................. jordali Petrov

- Vestiture on elytral disc abundant to base, granules on interstria 1 clearly larger than others........................... 4

4 Declivity sulcate from base to apex, margin elevated in middle (lateral view), apex truncate, larger granules only on interstria 1 ( Fig. 11 ).............................................................. sarahsmithae Atkinson & Flechtmann

- Declivity weakly sulcate at base, margin not elevated in middle (lateral view), apex appearing acute, larger granules on interstria 1 as well as on other interstriae at apex ( Fig. 10 ).................................. pedrosai Atkinson & Flechtmann

5 Smaller (1.8 mm), declivity narrowly concave, with a small granule on the declivital margin near the base and a similar one near the apex ( Fig. 6 )............................................................... bertii Atkinson & Flechtmann

- Larger (2.1 mm), declivity more broadly concave, with an acute denticle on the declivital margin near the base and two closely spaced denticles near the apex ( Fig. 8 ).............................................. maiai Atkinson & Flechtmann
